Introduction
The Model 2701-B PaveTracker Plus is an electromagnetic
sensing device that quickly gives an indication of the density
of asphalt pavement.
The advanced technology in the patented PaveTracker Plus
allows rapid and reliable measurements. The PaveTracker Plus
can be used on existing asphalt pavements or on freshly
placed mats. The unit is ideal for performing quick quality
control measurements to check for segregation, areas of low
density, and overall pavement uniformity.
The PaveTracker Plus is a precision device that is designed to
provide many years of trouble-free service. As any precision
device, the PaveTracker Plus requires reasonable care and
maintenance to ensure its accuracy and reliability. The user
should:
♦
Keep the unit clean and free of all road debris.
♦
Return the unit to Troxler for yearly re-calibration and
inspection.
♦
Ensure that the unit remains sealed at all times. There are
no field-serviceable components inside the unit.
Opening the case will affect the integrity of the unit and
therefore will void the warranty.
